Robert Dennard did not invent the battering ram, this was invented many 100's of years before he was even born. What Robert Dennard did invent was DRAM (Dynamic Random Access Memory).
A great helocopter
Count Ferdinand von Zeppelin, yes he did.
Ferdinand Adolf August Heinrich Graf von Zeppelin otherwise known as Ferdinand von zepelin invented the airship (such an original name!) called the zeppelin.
DirigibleActually, he invented the Zeppelin, but i guess a dirigible is just about the same thing...

It depends on your definition of "better", honestly. Better songwriters? Better musicians? Sold more records? In my opinion they are very evenly matched, and in fact are two of my top three bands of all time (the third being Yes). I've always considered Led Zeppelin of a higher level of musicianship than Pink Floyd. David Gilmour's guitar work is incredible in the meticulous nature it's planned out and executed, but Jimmy Page has more raw talent and can excel not only in planning out his guitar output (see the song "Achilles' Last Stand"), but also improvisation (see the numerous live versions of "Heartbreaker"). John Paul Jones is a better bassist than Roger Waters - and plays keybaords as well as Richard Wright! Comparing drummers I actually give the slight edge to Floyd's Nick Mason, as he has a much better sense of time than the late John Bonham, which IMO trumps Bonham's raw talent. And as far as vocals go, Robert Plant sings circles around every Floyd member. While Zep may win the musicianship battle, I believe that Pink Floyd wins the songwriting battle. Led Zeppelin never had a lyricist like Roger Waters, who could tell a story over an 80-minute double album just as well as he could a four-minute single. Coupled with Gilmour's sense of melody, they formed an incredible songwriting tandem. As far as total output, they're dead even. Floyd's best albums outshined Led Zeppelin's highest output, but unlike Floyd (who put out trach like A Momentary Lapse of Reason and The Final Cut) Zeppelin never put out a bad album. And the albums themselves had very few weak spots. The three-album stretch from III to Houses of the Holy was especially solid. So to sum up, I guess it's a bit of a cop-out, but to me they are equally good, all things considered.
